3 INTRODUCTION Congratulations on your purchase of this CO2Meter SAN-10 Personal CO2 Monitor. CO2Meter SAN-10 is a smart carbon dioxide (CO2) monitor using NDIR technology to provide long term stability. The SAN-10 Personal Safety CO2 Monitor is designed for employees who work in enclosed areas where carbon dioxide buildup may cause personal harm. It is designed to alert people in the area with excessive carbon dioxide gas. SAN-10 is shipped fully tested and calibrated and, with proper use, will provide years of reliable service. FEATURES Audible, visual strobe and vibrating alarms Large LCD display Man down alarm leveraging accelerometer technology Rugged design with protective rubber enclosure Heavy duty metal clip Front facing sensor unit Rechargeable Li-ion Battery 4.2v, 1500mAh 18+ hours per charge Black Micro USB cable and Wall USB charger Dual calibration methods: Ambient Air ( ppm) and Nitrogen (0-200ppm) Automatic atmospheric pressure compensation for CO2 concentrations No over-exposure or negative memory effects IP54 housing Stable NDIR sensor for CO2 detection MONITOR 1.

When LCD backlight is off, press either button to turn on the backlight. It will notturn the monitor off or change the C/ F setting. 1. Power button 1.1 When the Monitor is turned off, press to turn on the unit. 1.2 When the Monitor is turned on, press for 3 seconds to turn off the unit. When the unit is first turned on, it performs 5 seconds countdown for Monitor warm up, then enters normal display with current CO2, temperature, and humidity readings displayed. The monitor starts taking measurements when power on and updates readings every 2 seconds. The device can t shut off alarm, if power off will come back in alarm mode and must delay. 2. Temperature Units Button 2.1 Temperature Unit Press shortly to switch two temperature units: F and C. 4

5 2.2 Menu and Configuration Settings By pressing the temperature button for 11 seconds, the unit enters into Menu status. There are six menu items by pressing the temperature button shortly to loop switching between AIR, N2, LX.X, HX.X, A ON/AOFF and E (exit). To change the Low and High Alarm Thresholds, switch to L0.5 or H1.0 and press the button shortly to alter between defaults, press to select, E to exit. The menu items are described in the following table: Menu Items Functional Description AIR AIR means Ambient Air Calibration. User presses the power button to implement Ambient Air Calibration (300~600ppm). N2 N2 means Nitrogen Calibration. User presses the power button to implement Nitrogen Calibration (0~200ppm). H0.5/H0.5T/H1.0/ H1.5/H3.0 Current Defaults are L.0.5 H1.0 L0.5/L0.5A/L1.0/L1.5/L3.0 A ON/ AOFF E High Alarm Threshold setup. User presses the power button to switch the high alarm threshold: H0.5 (5000 ppm), H0.5A (5000 ppm), H1.0 (10000 ppm), H1.5 (15000 ppm), and H3.0 (30000 ppm). Low Alarm Threshold setup. User presses the power button to switch the low alarm threshold: L0.5 (5000 ppm), L0.5T (5000 ppm TWA), L1.0 (10000 ppm), L1.5 (15000 ppm), and L3.0 (30000 ppm). Setting Man down alarm function on/off. User presses the power button to switch A ON (allowing Man down alarm) or AOFF (prohibiting Man down alarm). User presses the power button to exit the menu. 5

6 3. Calibration There are two calibration methods: Ambient Air ( ppm) and Nitrogen (0-200ppm). By pressing the temperature unit button for 5 seconds, the monitor will enter CO2 calibration mode. While in calibration mode, press the temperature button quickly to switch between AIR (Ambient Air Calibration) or N2 (Nitrogen Calibration). Press the power button to confirm. Zero calibration requires 100% nitrogen (0% CO2) calibration gas, a flow regulator and flexible tubing. These can easily be obtained online: The Atmospheric calibration will not require additional materials but must be performed in outdoor ( ppm fresh air) during the entire procedure. See Section 2.2 Menu and Configuration Settings, to change settings. 4. Alarm Threshold There are default thresholds: 5,000 ppm CO2 (low alarm) and 1% CO2 (Short Term Exposure Limit) (high alarm). The alarm thresholds can be changed dependent on the user, to L0.5 (5000 ppm), L0.5T (5000 ppm TWA), L1.0 (10000 ppm), L1.5 (15000 ppm), or L3.0 (30000 ppm). If the measured CO2 value exceeds the define Low Alarm threshold, the alarm LED will flash red at 2Hz and the audio alarm de de de de will sound. If the CO2 level exceeds the High Alarm threshold, the LED will flash faster and the audio alarm will increase. To alert users in a noisy environment, the monitor will also vibrate. See Section 2.2 Menu and Configuration Settings, to change settings. 5. Automatic Atmospheric Pressure Compensation The displayed CO2 level is affected by atmospheric pressure or change in altitude. To insure maximum accuracy, this monitor has automatic atmospheric pressure compensation for CO2 concentrations by means of a digital atmospheric pressure sensor integrated in the unit. No calculations or maintenance is required. See Section 2.2 Menu and Configuration Settings, to change settings. 6

7 6. Man down alarm Falling by breathing dangerous gases can cause serious injury and even fatality to workers. If the Man down alarm function in SAN-10 is set on, SAN-10 can detect falls and send a man down alert which will activate the audible and visual alarms and alert other people in the area. The man-down detection uses a three-axis accelerometer to automatically monitor the user s movements. If a sudden fall/impact is followed by a lack of movement for 6 seconds, the alarm will sound. Turn off the alarm by pressing either of the two buttons. See Section 2.2 Menu and Configuration Settings, to change settings. 7. Reset Button Users can reset the unit by pushing a reset button through a hole on back of shell. MAINTENANCE Calibration The SAN-10 comes pre-calibrated from the factory. However, the CO2 sensor should be calibrated at least once a year, or as described in your company s safety procedures. You can perform the calibration yourself, or you can return it to CO2Meter for factory calibration at a nominal fee. The temperature and humidity sensors do not require calibration and should remain accurate for the life of your unit. Cleaning and Storage Attention: Do NOT use soap, alcohol, aromatic hydrocarbons, or chlorinated solvents for SAN-10 cleaning purposes. The front cover and case can be cleaned with a mild solution of detergent and water. Apply sparingly with a soft cloth and allow to dry completely prior to using. 7
